Mike,
I enjoy having that memory in the line with nylon leaders & tippets. For
me
it acts as cushion or shock absorber when you're hooked onto a fighting
fish. There were times on my past trip this past July on an Alaskan
River,
that some of the rainbows would turn their heads in a split second when
hooked, or come out of the water and shake their heads violently. My
friend
on the other hand has used fluorocarbon tippets, and there were quite a
few
times he had broken off from violent shakes
I was wondering your take on this?

There is rather a problem with the nomenclature here. All nylon has
memory, ( as do all thermoplastics). this is what makes them flexible
and elastic, and as this property is intrinsic, it can not be removed.

What happens to nylon line, is that after being stored in coils, or
kinked etc, the line retains the memory of that state, and in order to
remove that state, the memory of the line must be adjusted, by heating
and stretching.

If thermoplastics are bent or stretched beyond their memory capability
to restore themselves, and don´t break, they may lose even the
possibility of restoration in that specific area of the line.The
molecular orientation is damaged.

When one winds nylon line on to a plastic spool under tension for
instance, the line still tries to return to its original state as a
result of its intrinsic memory. This cause the line to contract, as
it was stretched when wound on to the spool. This causes massive
pressure on the spool, and can easily break or deform plastic spools,
but it also programs the memory of the line to remain in tight coils.

The only way to restore the line, is to heat it to a suitable
temperature, and stretch it very slightly, if kept straight and
rapidly cooled, it will stay straight, as the long molecule ( Polymer
chains), have been reoriented. The result is also stronger per se, as
longitudinally oriented molecules are stronger than any other
orientation. The result is also thinner. This is how "super strong"
nylon is made, it is stretched under the application of heat, after
manufacture, and then rapidly cooled. If ordinary is nylon kept
straight, BUT UNDER NO TENSION AT ALL, and allowed to cool naturally,
it will return almost completely to its original state.

The same applies to any thermoplastic. If you pull a piece of
polythene until it deforms, the resulting piece is much stronger when
pulling stress is applied, but it will not deform any further, if
stretched beyond this point, it will simply break.

Fluorocarbon lines are merely pre stretched nylon lines coated with
fluorocarbon. The fluorocarbon compounds used have lesser or no
memory properties, and sudden stress causes them to break, as they can
not extend.

There is no real point in using fluorocarbon lines at all, They are
not less visible to the fish, and they are intrinsically weaker than
any other thermoplastic copolymer ( Nylon is a copolymer) lines, not
least as as a result of their lack of memory, and abrasion resistance.
Their much vaunted sinking capabilities are overrated.

Also, as the dreaded Fortenberry also quite correctly pointed out,
they will last a very long time, as fluorocarbon coated line will not
degrade like ordinary nylon line.

I agree with you up to a point and that is why I also use ordinary
nylon, as it has a considerable degree of elasticity, ( due to
intrinsic memory), and cushions itself to a degree.

However, I don´t like curls and kinks in my leaders, as for some of
the techniques I use, they would cause me to lose a lot of fish, or
prevent correct presentation. So I normally warm my leaders up ( on
stream, in hot coffee etc), and stretch them very slightly, and allow
them to coll, so that they remain staright.

Thanks for clearing that up.
Yes, I stretch enough to take out the coils when casting, especially
when putting on new leaders and tippets.
I've seen those leather leader strengtheners, but never tried one, I've
just been using my hands to somewhat heat the leader material as I pull, at
least it's enough to take out some of the memory.

oh btw: I do enjoy your contributions to the group on fly-fishing....

Quite a few people use the leader straighteners, and they will in fact
work on the heavier nylon of butts etc, but if you use them on thin
points or tippets, thy will invariably damage the line. If you can
manage to straighten your leaders simply by pulling them through your
fingers, then this is the best way to go. It will usually remove curls
etc, if done properly, but ti wont remove kinks etc.

Just stretching the line, as some people seem to think, has no effect,
as the memory is not removed, heat is required to remove it. This
also applies to PVC fly lines. Stretching them as is often advised,
will not remove the memory, and will often only cause cracks in the
coating, and cause it to de-adhere form the non flexible core. To
remove the memory, put the line in very warm water, and then hold it
taut, ( but NOT overstretched) . This will make it perfectly straight
again, and it will remain so when it cools.

I much prefer them myself! But needs must when the devil ( or his
associates!) drives.

Just lost my leader wallet, and all of my leaders. Before I go out
and by a whole new set, figured I'd get your collective opinions on
your favorite mono-tapered leaders, and leader wallets. But also, let
me describe my experience, and complaints:

I generally use Orvis Super Strong Nylon leaders (usually 9ft, 4x -
6x), and very occasionally their flourocarbon. I love the lines for
their strength. I rarely break off a fish with this stuff. But, one
thing I really hated about this last batch was the memory. Every time
I'd get out a new leader I'd have to use my leader straightener 2-3
times, and even then it still had some curls. I tried out a different
brand today (I believe it was Dai Riki?), and it definitely had less
of a memory issue.

So - what're your favorite leaders, with little memory issues? Have
any of the magazines ever done head-to-head comparisons for this kind
of thing?

Then, for a leader wallet, I also used Orvis'. What I didn't like
about that, was that every time I'd get it wet (which was pretty
frequently), the fabric would take a while to dry. I'd prefer
something that didn't hold water at all, I think. Some kind of vinyl,
perhaps? Thoughts?

Thanks guys...

Don't store your leaders coiled. Put a couple of wire nails about 10-12
feet/3-4m apart in a climate-controlled room and use plastic coated
paperclips and rubber bands to store them. I've got such set-ups in a
number of places and if done high up (at or near the ceiling, at or near
the crown or picture moulding, etc.) and on the entry-door wall, they
all but disappear. At the very least, store them in as large a coil as
possible - put a cuphook in the back of a large piece of furniture and
store them there in large coils (this works for line, too).

I wouldn't use a leader wallet, but if I did, I'd only use it as a very
temporary carrying device, not a storage device. If one is determined
to use one, and one chooses a vinyl one with "envelopes" (i.e., one that
can trap water in the "envelopes"), one is faced with dampness issues.
They are "fabric" and "mesh" for a reason.

As to carrying a large CD wallet astream - WTF? As to storage, it
wouldn't be my choice, but hey, that's why there is chocolate and
vanilla. If you simply must have a wallet, and don't like the Orvis
one, maybe look for a sal****er rig wallet or a plastic worm wallet in
vinyl.

For carrying astream, I'd offer that simply sticking a couple
(individually) in small ziptop packets would suffice, and when returning
home, replace on the "rack." I personally like the small dental floss
"boxes" for a lot of things, including tippet, but YMMV.

As to the leaders themselves, I don't find all that much difference
between the multitude of brandings when comparing apples to apples,
material- and construction-wise. IOW, there are differences when
comparing mono to braid or mono to fluoro, but, um, "mono a mono," IMO,
there just isn't the vast differences some think there is - again, YMMV.

Just in case it was not clear, my main reason for using Maxima, is
because it has a matt finish. I consider this to be of paramount
importance, especially, but not only, for dry fly fishing. Most other
nylons have a smooth mirror finish, and the glinting from this can
spook fish badly. One may de-glint nylon by pulling it through a
paste of Fuller´s earth, but this is not necessary with Maxima. Also,
to make it sink, one merely needs to pull it through a very dilute
soap solution.

Unfortunately, and directly due to the "rough" matt finish, it is more
or less impossible to straighten fine Maxima using your fingers, or
(leader straighteners), the co-efficient of friction is very much
greater than that of smooth nylon, and usually it will break.

You're the 2nd person in this newsgroup that suggested Maxima
leaders for good reason, I'll have to try them.

You might also like to try the technique described at the bottom of

things, and can be made limp and straight by dipping them in boiling
water, and keeping them straight while they cool;

Just as an interesting aside, many guitarists boil their strings
before a concert, this "re-formats" the molecular orientation of the
string, ( both nylon and metal strings like steel or bronze wound),
and they sound crisper. The effect does not last long though, and can
only be used a couple of times at most, but it saves spending a lot of
money on brand new strings every time.

I think the deformation of the surface film is so much more visible than
anything having to do with the optical properties of the leader that unless
you can find a way to make the leader magically suspend a few thousandths
above the film, it's not worth worrying about.

One last point which may be of use to some. Many years ago now, it was
common for people to wind a few leaders around their hats. This works
very well. One removes any memory at home, and winds the resulting
straight limp leaders around the hat. I have an Orvis Gore-tex wide
brimmed hat, which I use expressly for this purpose. I have had this
hat a very long time now, over thirty years. I made some special
lambswool hat bands for it, with a short piece of elasticated material
( knicker, or "shirring" elastic). usnig these I can carry half a
dozen leaders easily, and because they are in large coils, they never
cause any problems.

The lambswool bands ( dyed brown in order to be less conspicuous), are
also very useful for sticking wet flies in. (Wont work for barbless
hooks of course) The hat band shown is a sal****er seatrout band.

Of course, this only works if you use such a hat.

If a line is sunk, it does not deform the surface film. If a line is
treated with a suitable wetting agent, it sinks immediately, because
it removes the surface film. While there are some dry fly designs and
techniques which allow one to fish with a sunken leader, the majority
rely on a floating leader, as a sunken leader merely pulls the fly
under.

Mirror finish nylon is more visible under water as well. Easy to
see,just put some in a glass of clear water and view it.
